Methods: Nineteen adolescent state-level weightlifters were assigned into isokinetic or isotonic groups. All participants were recruited from a pool of weightlifters with standardized training program provided by their coach. Series of immunological tests were carried out before the commencement, immediately upon the completion, and a month after the cessation of the additional training program to evaluate total leukocytes and lymphocytes count.
Results: The results revealed a significant time and group interaction and main effects of time on mean total leukocytes (P < 0.05). Mean total leukocytes count at posttest decreased in both groups. In isotonic group, it was further decreased following 1 month of training cessation (P < 0.05) but not in the isokinetic group. However, the decrement was not high and the values were in the normal range. No significant time and group interaction was observed in total lymphocytes and its subsets count.
Conclusions: Eight weeks of isokinetic and isotonic additional training with emphasis on shoulder joint only affect mean total leukocytes count in state-level adolescent weightlifters.
OBJECTIVE: This article provides the reader with an understanding of the natural history, pathophysiology, phases and clinical features of idiopathic frozen shoulder. It also outlines patients at risk of developing idiopathic frozen shoulder and addresses an evidence-based conservative approach to the management of this condition.
DISCUSSION: The primary care physician plays a pivotal part in the identification and management of idiopathic frozen shoulder, with the vast majority of patients responding to conservative management. A shared care approach with a skilled physiotherapist is essential.
MATERIALS AND METHODS: The AGA is a new measured angle formed between the line from midglenoid to lateral end of the acromion with the line parallel to the glenoid surface. The AGA was measured in a group of 85 shoulders with RCT, 49 with GHOA and 103 non-RCT/GHOA control shoulders. The AGA was compared with other radiological parameters, such as, the critical shoulder angle (CSA), the acromion index (AI) and the acromiohumeral interval (AHI). Correlational and regression analysis were performed using SPSS 20.
RESULTS: The mean AGA was 50.9° (45.2-56.5°) in the control group, 53.3° (47.6-59.1°) in RCT group and 45.5° (37.7-53.2°) in OA group. Among patients with AGA > 51.5°, 61% were in the RCT group and among patients with AGA < 44.5°, 56% were in OA group. Pearson correlation analysis had shown significant correlation between AGA and CSA ( r = 0.925, p < 0.001). It was also significant of AHI in RCT group with mean 6.6 mm (4.7-8.5 mm) and significant AI in OA group with mean 0.68 (0.57-0.78) with p value < 0.001 respectively.
CONCLUSION: The AGA method of measurement is an excellent predictive parameter for diagnosing RCT and GHOA.
METHODS: We retrospectively reviewed all RSAs performed in 7 centers from 1998 to 2010. The inclusion criteria were primary glenohumeral osteoarthritis with B1, B2, B3, or C glenoid. Forty-nine shoulders in 45 patients fulfilled the criteria. Bone grafting was performed in 16 cases. Clinical outcomes were evaluated with the Constant score (CS) and shoulder range of motion.
RESULTS: The mean total CS increased from 30 preoperatively to 68 points (P < .001) with significant improvements in all the subsections of the CS and range of motion. Scapular notching was observed in 20 shoulders (43%), grade 1 in 5 (11%), grade 2 in 7 (15%), grade 3 in 5 (11%), and grade 4 in 3 (6%). The glenoid bone graft healed in all the shoulders. Partial inferior lysis of the bone graft was present in 8 cases (50%). Scapular notching and glenoid bone graft resorption had no influence on the CS (P = .147 and P = .798).
CONCLUSION: RSA for the treatment of primary glenohumeral osteoarthritis in patients with posterior glenoid deficiency and humeral subluxation without rotator cuff insufficiency resulted in excellent clinical outcomes at a minimum of 5 years of follow-up.
Methods: Nineteen young state-level weightlifters performed concentric strength tests of the upper limbs using an isokinetic dynamometer. Peak torque/body weight was measured for each weightlifter in dominant and non-dominant limbs.
Results: Peak torque/body weight was significantly different in external rotation (p 0.05). Time to peak torque in external rotation was less in the dominant than in the non-dominant limb. However, opposite results were obtained in external rotation, whereby time to peak torque was longer in the dominant limb compared to the non-dominant limb. Similarly, no significant difference was found between dominant and non-dominant limbs in terms of average power (p > 0.05).
Conclusions: The findings of this study may help in establishing potential imbalance in variables of muscular contractions between dominant and non-dominant limbs of weightlifters. This may help to maximise performance and minimise potential shoulder injury.
